Can the exponent in the denominator be subtracted from the exponent in the numerator when the based are different? Explain

Respuesta :

Answer:

No, Sorry.

Step-by-step explanation:

Since the bases are different, you'll have to change them even if they have a exponent or not. If you dunno how to make the denominators the same, just multiply the two by eachother.

Example) 1/2 - 3/4

[tex] \frac{1}{2} - \frac{3}{4} [/tex]

Multiply 2 and 4 together, and then multiply the 4 to the one also. Multiply 2 to four and also to the 3.

[tex] \frac{4}{8} - \frac{6}{8} [/tex]

The subtract from there.

[tex] \frac{ - 2}{8} [/tex]

and then Reduce (if needed.)

[tex] \frac{ - 1}{4} [/tex]
